That is exactly the work of the establishment review that's under way right now.
It's a little of all the things you just said. The former establishment was geared to delivering the ships' companies of 10 Kingston-class ships and the supporting functions around that. You can do a calculation based on ratios and the like to force-generate the required numbers.
We're adjusting that now to eventually meet the 10% augmentation target across the surface warship fleet of the navy. A lot of the calculations are based on that and the supporting functions around it. In a nutshell, it's essentially a very complicated task that some very good staff are working on right now.
